LQM18PN1R5MFHD - Murata Electronics

LQM18PN1R5MFHD Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQM18PN1R5MFHD?
  The recommended land pattern for LQM18PN1R5MFHD is a rectangular pad with a size of 1.8mm x 1.3mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a solder mask opening of 1.8mm x 1.3mm.
• Can I use the LQM18PN1R5MFHD in a high-temperature environment?
  The LQM18PN1R5MFHD is rated for operation up to 125°C, but it's recommended to derate the current rating according to the temperature derating curve provided in the datasheet. Above 125°C, the inductor's performance and reliability may be compromised.
• How do I handle the LQM18PN1R5MFHD during PCB assembly to prevent damage?
  Handle the LQM18PN1R5MFHD by the edges or the tape, avoiding touching the component body or the terminals. Use a vacuum pick-up tool or tweezers to handle the component. Avoid bending, flexing, or applying excessive force to the component or its leads.
• What is the equivalent series resistance (ESR) of the LQM18PN1R5MFHD?
  The ESR of the LQM18PN1R5MFHD is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on the inductor's design and materials.
• Can I use the LQM18PN1R5MFHD in a high-frequency application?
  The LQM18PN1R5MFHD is designed for general-purpose use and has a self-resonant frequency of around 100-200 MHz. While it can be used in high-frequency applications, its performance may be limited by its self-resonant frequency and parasitic capacitance. For high-frequency applications, consider using a more specialized inductor designed for high-frequency use.
